Thanks! I see a sirfid, but I don't recognize it.... I've never met Merodon

As they say, "come to our Kolyma". Near St. Petersburg, at best, you can find Merodon equestris, a pest (possibly imported from Europe). Other Merodons are found much further south. So, in the Crimea, there are already about 15 species of them, and near Kiev-1-2. In some places, in steppe reserves, there are a lot of them during the summer, but outside of them they are almost extinct. There are no more than a few species in the Ciscaucasia, the Volga region, and the Black Earth Belt. The Caucasus is richer, especially Transcaucasia. But the group is poorly studied and it is almost impossible to determine them reliably by the "Green" Determinant (vol. 5, part 2, see Stackelberg, 1970 - sem. sirfids).

Thanks for the information.
I think I got one copy from Moldova from Ripper. It's a pity that the" green " is not clearly defined (I don't have another one). And the Dutch site (with the identification of European sirfids) does not open for some reason.
Well, in the spring I will look for Merodon equestris....

If you want, you can post or send a photo of the Moldovan copy on the top and side - I can try to identify it. And all the existing qualifiers, including the Internet Golladsky site (Van Veijenovsky, I think? Although I may be wrong...), they are incorrect, although this site has very complete information and illustrations. Now a well-known sirphidologist from Serbia is working on a monograph of the genus, but it will not be published soon... And try to look for M. equestris in greenhouses (or in them), where daffodils, hyacinths, tulips, etc.are grown, although it is in nature on flowers, from late spring to mid-summer. It looks like a small bumblebee.
